Manu,

I have realligned my dish to Astra 28.2 degrees instead of the Astra
19.2 degrees.

I grabbed the source from your site from yesterday and had to apply only
the following:

void mantis_dma_start(struct mantis_pci *mantis)
{
        dprintk(verbose, MANTIS_DEBUG, 1, "Mantis Start DMA engine");

        mantis_risc_program(mantis);
        mmwrite(cpu_to_le32(mantis->risc_dma), MANTIS_RISC_START);
        mmwrite( mmread( MANTIS_GPIF_ADDR ) | MANTIS_GPIF_RDWRN,
MANTIS_GPIF_ADDR); // new
//      mmwrite(MANTIS_GPIF_RDWRN, MANTIS_GPIF_ADDR); // old

        mmwrite(0, MANTIS_DMA_CTL);
        mantis->last_block = mantis->finished_block = 0;

        mmwrite(mmread(MANTIS_INT_MASK) | MANTIS_INT_RISCI,
MANTIS_INT_MASK);

        mmwrite(MANTIS_FIFO_EN | MANTIS_DCAP_EN
                               | MANTIS_RISC_EN, MANTIS_DMA_CTL);

}

Now I can do a Scan and get channels. Kaffeine and xine tune as wel as szap.

    

This is fine, looks fine, sounds fine.

  

I'm using only this patch to your source so I do not have distortion of my picture.

Did some more testing today with the following results:

1. My total cable between computer, rotor and lnb was to long. I could see that my rotor signalled power low a lot and it was unstable with my other dvb card. I pulled about 2,5 meters out of my ~30 meter long cable and I had a stable power signal again all the way up to my lnb with a rotor in between.
2. The mantis driver with "changeset 4491: 276006546e29", and the above path, does support DiseqC 1.2 now. I can control my rotor without problems. So this is great news for me.
3. I have not tested this completely but I cannot get all the transponders on each satellite. I tested Astra 19.2 and 28.2 so far and not all the transponders can be tuned into. I will try to create a list of working and not working transponders and post the result to this list. Maybe my LNB is of because I have the same result within Windows. Hope this is not a problem of the card it self.


Regards,

Michel.
